It sounds quite likely. We'll have to look into it.

Now I wonder if that's also what those Google apps are doing...

They are user mode apps and you allocate kernel memory and lock it. They should not have any impact.

If that were true, they really wouldn't have any impact. That's known not to be the case :)

Note that as far as we know, it's not Google Chrome etc. that's causes trouble, but Google's crash reporter. Somehow I have the feeling that they may have considered it important to get kernel stack traces and enabled that registry setting... just a wild guess at this point.

ok, it seems to work now and in my case the cause was a tool called Prio (http://www.prnwatch.com/prio.html). This is a tool which saves the priorities and CPU affinities for selected programs. This is done by injecting a DLL into each program. And this injecting seems to cause the memory allocations failures.

And mybe the Google crash reporter also injects a DLL to maybe create custom dumps and so also causes this. I'll watch this the next days and hope that this was the fix.

The error log said:
Unable to allocate and lock memory. The virtual machine will be paused. Please close applications to free up memory or close the VM

But the VM is not paused, just crashed. I don't have special processes neither any google stuff. I started too much VM and other application, I see. I ran out of memory actually, okay, but please, stay in paused mode (as the message promise it), I don't like this guru :(

See the ticket 1021, https://www.virtualbox.org/ticket/10121

For it works now fine. Prio was really the cause
